Besides the technology development and population growth, the electric energy consumption has increased and this will cause expansion of electric networks. The expansion of networks requires site selection of new substations and increasing the capacity of existing substations. On the basic, optimal site locating of transmission substations as the source energy supplier of distribution networks is the major goal of network administrators which leads to many advantages like decreasing power losses, minimizing feeder rooting costs and considering civil constraints. This paper, by using the geographic information system abilities in the field of geo-referenced information management and spatial analysis implementation, presents a heuristic algorithm to determine the count, capacity, location and optimized service area for each substation with respect to electric constraints (such as voltage drop and power losses), geographic factors (like topography, land use, accessing, military area and environmental limitations) and minimizing network expansion costs.
